I am not a good swimmer, and have entered two triathlons and need to learn. My instructor pointed out the failings in my freestyle stroke, however trying to concentrate on body position, legs and arms breathing then became an issue. I did some 'Google' research and the 'Center Snorkel' seemed to be the answer. I have now used it at a number of lessons and it has been commented on how my freestyle stroke has improved. I now do 4 lengths warm up using the snorkel to get things right and then again at the end as warm down. Once you get over the 'looks' from other swimmers, you will find it a real help when trying to improve your swimming. Many teams are now using the snorkel so I am sure they will become more commonplace in pools .
I have bought a lot of Decathlon products in the past and always found them to be good quality and competitively priced and this item is just that. Once you are swimming with it, apart from being able to breath underwater, you will not notice you have it on.
Can concentrate on swimming
